There's a reason why the mortise-and-tenon is a go-to joint for a leg-to-apron joint—it's strong, and it resists racking. But  if your furniture designs feature slender, curving legs, there sometimes is not room for a traditional mortise-and-tenon. That's when Timothy Coleman gets creative, employing different arrangements from each side of the leg, and varying the length, thickness, and number of tenons. With a wide apron, he stacks and interlocks long tenons, taking advantage of the greater glue surface, When the apron is not wide, he sometimes makes it thicker and uses double tenons. When even more strength is needed, he adds a stretcher.
